Leners Patent No. 88,656, dated April o, 1869.

To all whom 'it may concern.-

Be it known that we, FRANzIs A. ODERMATT and FRANK ETTLIN, of the city and county of San Fran cisco, State of California, have invented an Improved Writing and Drawing Fountain-Pen; and we do hereby declare that the following description and accom panying drawings are suicient to enable any person skilled in the art or science to which it most nearly appertains, t0 make and use our invention or imprvements without further invention or experiments.

The nature of our invention is to provide a new and useful improvement in writing anddrawing fountainpens, the two combining the same general principles, which consists in providing a barrel, or fountain, with flexible sides, so that, by gently pressing with the fingers, the ink is forced ont through a small pipe, upon the back of the pen, in the desired quantity. The flow of ink is checked wholly or partially by a small stopcock, which is placed a little below the end of the barrel.

To more fully illustrate and describe our invention, reference is had to the accompanying drawings, and letters marked thereon, of which- Figure 1 is a side view.

Figure 2, a bottom view.

Figure 3, a longitudinal section.

h Figure 4 shows the attachment of a drawing-peu, 1n re a is the barrel, or fountain, which is cut awayat Vboth sides, to admit a flexible tube, b, which is so packed, or cemented to the interior of the barrel, as to be water-tight, and may swell out a little larger than the circumference of it.

The thumb vand fore-linger of the Writer rest on the lexible sides in using, and, by gently pressing it, the ink will flow out at the end of the small culved supply-pipe, c, at the lower end of the fountain, upon the back of the pen, in thedesired quantity.

A small stop-cock, d, is provided for the pipe, which, by turning, will check the ow entirely, or only partially, as desired.

For a greater convenience in holding the fountai raised bars, e e,lare placed above and below, and horizontally with it. The fore-finger may rest against the which may be of cork, rubber, or metal, with a screw-- connection.

An air-pipe, g, leads through the head into the barrel, and has a small cock, g', to let the air escape from time to time, if the pressure should become too great.

When the pen is not in use, both cocks should be shut.

In the application of our invention to a drawing-pen, the same general construction may be followed, with the exception that the end ofthe supply-pipe be carlied below the regulating-screw,' and be curved a little more, to carry it to the centre of the two blades, or lips, and when a communication is once had -ot' the ink to the point of the pen, it will flow regularly. Y

It would be well, however, before commencing to write, 'or draw, lto wipe the back of the penand point with a wet sponge, so that the ink will more evenly and readily flow to the point.

Y In .filling the fountain, the lower cock is to he shut, and the stopper removed, when the ink is poured in at the top.

Bythis device, we have a fountain-pen thatcan be used a much longer time than other fountain-pens, without replenishing.

Having thus described our invention,

What we claim, and desire `to secure by Letters Pat- The pen described, consisting of the hollow handle a, pivoted with the flexible parts b 11, and guard-pieces ee, with tube c, with cock d, and head j, withfcock g,the whole being combined and 'arranged as described, for the purpose set forth.

In witness whereof, we have hereunto set our hands and seals. f
